A bushing 14 is arranged between the lower mounting bases 13, and a detection upper roller 15 is arranged on the inner side of the bushing 14. A measuring base plate 16 is arranged on the side of the mounting plate 11, and the measuring base plate 16 is located below the mechanism distance sensor. A rotating shaft 24 is arranged between the intermediate trays 6, and a drive wheel 25 is arranged on the surface of the rotating shaft 24. There are three sets of drive wheels 25, and the drive wheel 25 in the middle is in contact with the detection upper roller 15.

Two sets of pressure roller assemblies 10 are arranged on the surface of the pressure roller fixing shaft 9. The two sets of pressure roller assemblies 10 are connected to the drive wheels 26 on both sides. 5 are in contact with each other. Two sets of belt trays 5 are provided on the inner side of the conveyor profile 1, and an intermediate tray 6 is provided between the belt trays 5.

A mounting plate 11 is provided on the side of the mounting bracket 4, and a laser rangefinder sensor 12 is provided on the surface of the mounting plate 11. A lower mounting seat 13 is provided at the lower part of the mounting plate 11, and a guide post 18 and a compression spring 26 are provided between the lower mounting seat 13 and the mounting plate 11. A bushing 14 is provided between the intermediate trays 6, and a detection roller 15 is provided on the inner side of the bushing 14. A rotating shaft 24 is provided between the intermediate trays 6, and a drive wheel 25 is provided on the surface of the rotating shaft 24. There are three sets of drive wheels 25, and the drive wheel 25 in the middle is in contact with the detection roller 15. A fixed seat 8 is provided at the lower part of the conveyor profile 1, and a pressure roller fixing shaft 9 is provided on the inner side of the fixed seat 8. Two sets of pressure roller assemblies 10 are provided on the surface of the pressure roller fixing shaft 9. The pressure roller assembly 10 includes a pressure roller arm 19 connected to the pressure roller fixing shaft 9, and a connecting shaft 20 is provided on the inner side of the pressure roller arm 19. A fixing post 21 and a pressure roller torsion spring 22 are provided on the surface of the pressure roller fixing shaft 9. The other end of the pressure roller torsion spring 22 is in contact with the connecting shaft 20.A pressure roller body 23 is disposed between the pressure roller arms 19, and the pressure roller body 23 is in contact with the drive rollers 25 located on both sides. A conveyor belt 7 is located between the pressure roller body 23 and the drive rollers 25. When the conveyor belt 7 operates, the pressure roller body 23, through the torque of the pressure roller torsion spring 22, causes the conveyor belt to make close contact with the drive rollers 25, generating friction and thus driving the drive rollers 25 to rotate. The detection upper roller 15, with its compression spring 26, continuously applies downward pressure, causing the detection upper roller 15 to make close contact with the drive rollers 25 and rotate simultaneously. When encountering uneven areas, the detection upper roller 15 will cause the lower mounting base 13 to move upward, thereby moving the measuring base 16 located below the laser range sensor 12. The laser range sensor 12 detects the displacement of the measuring base 16, thus transmitting the signal to the processor for subsequent rejection assembly processing.

[0023] Further improvements, such as Figure 3 As shown: The interior of the intermediate tray 6 is provided with a through hole 17, and the through hole 17 is located at the connection between the detection upper roller 15 and the drive wheel 25. The design of the through hole 17 facilitates the contact between the detection upper roller 15 and the drive wheel 25.

[0024] Further improvements, such as Figure 4 As shown: The pressure roller assembly 10 includes a pressure roller arm 19 connected to the pressure roller fixed shaft 9, and a connecting shaft 20 is provided on the inner side of the pressure roller arm 19. The surface of the pressure roller fixed shaft 9 is provided with a fixing post 21 and a pressure roller torsion spring 22. The other end of the pressure roller torsion spring 22 is in contact with the connecting shaft 20. A pressure roller body 23 is provided between the pressure roller arms 19, and the pressure roller body 23 is always in contact with the conveyor belt 7 through the torque of the pressure roller torsion spring 22.

[0025] Further improvements, such as Figure 1 As shown: The conveyor belt 7 is located between the pressure roller body 23 and the drive wheel 25. The pressure roller body 23 relies on the torque of the pressure roller torsion spring 22 to make the conveyor belt and the drive wheel 25 in close contact to generate friction, thereby driving the drive wheel 25 to rotate.

[0026] Further improvements, such as Figure 3 , 5 As shown: There are two sets of guide posts 18 and the compression spring 26 is located between the two sets of guide posts 18. The guide posts 18 are inserted into the interior of the lower mounting base 13. The combined design of the two sets of guide posts 18 and the compression spring 26 enhances the stability and guidance of the detection roller 15 during its up and down movement, and reduces the detection error caused by vibration or offset.

[0027] Further improvements, such as Figure 3As shown: The measuring base plate 16 is arranged in an L-shape and is fixedly connected to the lower mounting base 13 by bolts. The L-shaped measuring base plate 16 is not only easy to install and fix, but also effectively increases the contact area with the laser rangefinder sensor 12, thereby improving the sensitivity and accuracy of signal detection.

[0028] Working Principle: The conveyor belt 7 starts to run under the drive of the motor. The pressure roller body 23 is pressed tightly against the conveyor belt 7 by the torque of the pressure roller torsion spring 22, so that the conveyor belt 7 and the drive wheel 25 generate sufficient friction to drive the drive wheel 25 to rotate. This step ensures that the material can be driven by a stable driving force during the conveying process, avoiding slippage or stagnation, improving the stability and efficiency of material conveying, and providing a reliable foundation for subsequent thickness detection. The detection roller 15 is given continuous downward pressure by the compression spring 26, so that it is in close contact with the drive wheel 25 and rotates synchronously. When the material passes through the detection area, if there is unevenness or thickness change on the material surface, the detection roller 15 will move up and down accordingly, thereby driving the lower mounting base 13 and the measuring base plate 16 to move, realizing real-time dynamic detection of material thickness. It can promptly detect and handle materials with abnormal thickness, ensuring the stability and consistency of product quality. The laser range sensor 12 detects the displacement of the measuring base plate 16 and transmits the signal to the processor. The laser range sensor 12 monitors the displacement changes of the measuring base plate 16 in real time and converts these changes into electrical signals and transmits them to the processor. The processor analyzes and processes the received signals to determine whether the material thickness meets the requirements. High-precision laser ranging technology enables accurate measurement and rapid assessment of material thickness. Once abnormal thickness is detected, the processor immediately triggers the rejection assembly to remove the material, preventing defective products from proceeding to the next process. Based on the processor's judgment, the rejection assembly precisely removes the non-compliant material from the production line. This step ensures that only materials meeting quality requirements can proceed to the next processing stage.

It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics.
